Admittedly we’ve sounded the alarm for the dual movie pack of Atlantis: The Lost Empire/Atlantis: Milo’s Return before, but this time we’re almost certain it’s going to happen. Ahead of any official announcement (which is expected later today if the pattern holds), Amazon.com has begun accepting pre-orders for the movie/sequel pair on Blu-ray for a release date of June 11, 2013. This was not the case when we believed it to be released alongside of Mulan, Brother Bear and Hunchback of Notre Dame and their respective sequels earlier this year.
